Types of Cyber Security Attacks
There are various types of cyber security attacks. Some of the cyber security attacks are mentioned below:
Malware is software that performs malicious actions, such as data corruption or taking over a system, on a device or network. Malware makes its way into a system through a malicious link or email that is clicked by a user. Once a system is infected by malware, it can block access to the critical components of your network, gather sensitive data, and damage the system.
Spyware is a form of malware that stays concealed on a device and transmits real-time data, such as bank details and passwords, covertly to the host.
When a hacker attempts to bait individuals into disclosing critical information, such as personally identifiable information (PII), banking details, and passwords, it is known as phishing. An email can trick the email recipient into providing confidential information or downloading malware into the system by clicking on a hyperlink in the email.
Distributed Denial-of-Service (DDoS)
DDoS attacks are aimed to disrupt a computer network by overwhelming the servers and requests. During a DDoS attack, the network gets flooded with superfluous requests from hundreds or thousands of IP addresses that overload the system and keep the legitimate requests from being fulfilled. It causes the target system, such as a website, to crash from an overload of demands.
As the name suggests, ransomware is a type of malware that blocks access to a system or data until a ransom is paid. The attack involves data encryption on the target system that renders all files inaccessible and demands a monetary ransom to give back access to the owner again. These attacks can be low-level nuisances or even have damaging consequences.

A zero-day exploit is a cyber attack that happens the same day a flaw occurs in software, hardware, or firmware. Because the software flaw is recent, it is hard to put up a protection system in place immediately.
Advanced Persistent Threats (APTs)
An APT refers to an unauthorized user gaining access to a system or network and remaining there without being detected for a long period.
Named after the Trojan Horse of ancient Greek history, this type of malware or code initially acts as a legitimate standard application or file and tricks one into loading and executing the malware on their device. Once inside the host system, the Trojan releases the malicious code that has the potential to damage or steal data or execute some other harmful activity on a network.
A wiper attack is a type of malware that intends to wipe out the hard drive of the computer that is infected by the attack. This involves wiping, overwriting, or removing data from the victim’s computer. These kinds of attacks are primarily destructive and often do not involve the demand for a ransom. Sometimes, wiper attacks are used to cover the tracks of a separate data theft that is being carried out simultaneously. Wiper attacks aren’t covert for the most part, as they are not meant to linger quietly in the background.
Intellectual Property Theft
Intellectual property theft is stealing or using someone else’s intellectual property without their permission.
Man-in-the-middle Attack (MITM Attack)
A MITM attack is when an attacker inserts themselves in the middle of a communication between two parties, such as a user and an application, and attempts to steal information. During a MITM attack, the attacker can eavesdrop or impersonate one of the parties, making it seem as if the normal exchange of information is underway.
A drive-by-download attack is a download that happens without a person’s knowledge, often installing a malicious program such as spyware, malware, or virus. The download can happen in two ways:
- Downloads that happen after the authorization is given by the user but without understanding the consequences; for example, downloads that install an unknown or counterfeit executable program.
- Downloads that happen without the knowledge of the user; for example, a computer virus, spyware, malware, or crimeware.
Malvertising otherwise referred to as malware advertising, is online advertisements that spread malware and compromise systems. Generally, this happens through the injection of malicious code into ads.
Rogue Security Software
Rogue security software is a malware and internet fraud that is disguised as real software; it tricks users into believing that their computer has a virus and convinces them to pay for a fake malware removal tool that installs malware on their computer.
Sometimes, natural disasters can disrupt the data center that houses the software.

Cyber Security Types
In the entire process of network security, numerous techniques are employed to prevent malicious activities and secure the network by only allowing the entry of authorized users. The network is secured with a firewall that acts as a barrier between the network system and external attacks.
Similar to protecting networks, having a strong app-level security system is also important. Application security is designed and implemented usually before deploying the application and requires a strong password from the user. Some of the techniques involved in application security are two-factor authentication, security questions, and more.
With most organizations moving toward the cloud for data storage, a majority of the cloud platforms, such as Google Drive, Microsoft OneDrive, Apple iCloud, etc., are being used predominantly. This has led to further need for their security. This type of security is known as cloud security. Since a huge amount of confidential data is involved, ensuring the security of the cloud is necessary at all times. Some of the techniques used are end-user interface, data storage security, backup plans, and more.
Operational security involves identifying sensitive data and possible threats, analyzing vulnerabilities and threat levels, and implementing plans to mitigate threats. Operational security refers to utilizing risk management to identify potential threats and prevent sensitive information from getting into the wrong hands.

Need of Cyber Security
There is no indication that the reliance on technology will ever subside. This means that more sensitive information and bank details will be stored in cloud storage services, which can result in frequent data leaks and identity thefts. So, it is crucial to be aware of Cyber Security.
From using computer systems every day to the rise in cloud services, we have to be concerned about a myriad of Cyber Security threats. Governments around the world are turning their attention to cybercrimes. There have been major cyberattacks over the years; for example, the Melissa virus attack in 1999, the WannaCry ransomware attack in 2017, the NASA cyberattack in 1999, etc. Councils such as the National Institute of Standards and Technology (NIST) have begun releasing frameworks to help everyone understand the security risks, Cyber Security measures, and prevention methods.
Cyberthreats can arise at any level in an organization and the attacks are getting more sophisticated day by day. For example, the WannaCry attack flooded millions of systems across the world in May 2017. Organizations are now aware of such attacks and spend loads of time and money on Cyber Security technologies and processes. Reports state that the Indian government has increased the funds allocated for Cyber Security in the IT industry. For 2020-2021, the figure has reached INR170 crores from INR102 crores. As per the report by the Data Security Council of India, the country’s Cyber Security services industry is projected to reach US$7.6 billion by 2022. The world has witnessed a shift to remote working; hence, the importance of cyber security now is more than ever before.
